Otago Harbour tidal power idea gets boost  

Posted by Big Gav in , , ,

The Otago Daily Times has an article on a tidal power project proposed for Dunedin's harbour - Otago Harbour tidal power idea gets boost.

There are renewed calls for Dunedin to consider investing in tidal power generation in Otago Harbour, stimulated by progress towards a $600 million scheme north of Auckland.

Auckland-based power company Crest Energy is seeking consent for a 200-turbine, 200-megawatt scheme, costing about $600 million, at the entrance to Kaipara Harbour. The scheme would be the first of its kind in New Zealand, and could power 250,000 homes.

The Environment Court has given a positive recommendation to Conservation Minister Tim Groser, while requesting work to address lingering environmental concerns.

The progress encourages David Tucker, of Dunedin, who argues a similar scheme should be considered for Otago Harbour. Mr Tucker, a semi-retired consultative engineer and former Dunedin City Council consultant, said Otago Harbour could be as effective as a source of renewable energy.

He envisaged turbines on the sea floor at the mouth of Otago Harbour, driven by the tide to generate power, or a barrage from Port Chalmers to Portobello - or both.

NZ has many potential tidal flow opportunities. There are several tidal flow systems under development overseas. At least two in UK comprise a twin generator attached to a hydrofoil, and function well. The old idea of erecting an envoironmentally unsatisfactory barrage is unnecessary. Kaipara harbour proposal envisages an open turine on the sea floor. Some investment in tidal flow system R & D is better than wasting investment on CO2 sequestration etc.

Good grief! Someone shoot that barrage idea down ASAP. Best method yet to destroy immensely valuable fish breeding areas and more often than not, all sorts of birdlife feeding and breeding.
Tidal flow technology offers the best returns with the least impact.
